Dulcolax can cause cramping, stomach upset, feeling faint, and the feeling that you "have to go right now".

You have to be comfortable with putting the medicine in your rectum.

Suppositories can cause slight rectal burning.

How it works

Dulcolax (Bisacodyl) is a stimulant laxative that you can take by mouth or in a suppository. It causes waves of contractions (peristalsis) in your intestine muscles to push stool through. It also makes stool more watery.

Risks and Warnings for Dulcolax (Bisacodyl)

Stop taking Dulcolax (Bisacodyl) and call your doctor right away if you have nausea, vomiting, pain or bulging in your belly that doesn't go away, have rectal bleeding, and no bowel movement after taking. These may be symptoms of a bowel blockage (bowel obstruction) which is serious.
